Upper and lower intake for my 351W swap. I'm going to get a dremel and do a little bit of work on the lower intake.

Exhaust manifolds for 5.8W swap. These are probably going to switched out in favor of BBK shorty headers. P/N BBK-35110
|
|
|
Rebuilt 19lbs injectors for my 351W swap.
|
|
|
The 351 on the ground in my garage, it will sit here until I get around to putting it up on an engine stand.
|
|
|
As you can see the motor is filthy, the water pump, distributor, and pretty much everything will need to be replaced.
|
|
|
TFI is mounted on the dist, not a good thing, since they are prone to heat soak. Scored one for $50 bucks with a remote mounted TFI.
|
|
|
Water pump and brackets removed.
|
|
|
Upper intake removed. Looks like something made a nest in there, probably a rat, or someother kind of rodent.
|
|
|
The starter looks a lot bigger than the one on my 302, could be an aftermarket high torque one.
|
|
|
Stock distributor with the earlier style TFI mounted to it. Since my Bronco has the TFI mounted on the fire wall, I'll need to go with a dizzy from a later year 351.
|
|
|
The intake plenum was dirty but not filthy.
|
|
|
Lower intake manifold removed.
|
|
|
(Update) This whole is a normal part of the block casting process and will not harm the engine in any way. Not sure what this hole is from or if its supposed to be there, I did not notice any damage to the block otherwise.
|
|
|
Stock 351 heads. I'll be reusing this, although they will have new springs installed.
|
|
|
Finally have it on a engine crane, I don't think the stand I have is sturdy enough.
|
|
|
The timing chain cover came off, but the harmonic balancer needs to be pulled before that will come off.
|
|
|
This is not the way to mount the engine to the engine stand. Notice the bolts are bending they need to be shimmed out with washers and use shorter bolts.
|
|
|
Removing the valve spring, got this tool at Discount for $20 bucks.
|
|
|
This is the proper way to shim the block on the engine stand. The block is now tightly pulled up to the stand.
|
|
|
Cam bearing will have to be removed by the machine shop. I just don't have the tools to get this done.
|
|
|
Engine back from machine shop bored .40 over.
|
|
|
Still need cam, lifters and timing chain.
|
|
|
New parts for the engine, motor mounts, waterpump, timing chain, tensioner pulley and fuel pressure regulator.
|
|
|
Installed new Melling oil pump.
|
|
|
Cleaned the old T/B, polished the butterflys and hit it with a couple fo coats of paint.
|
|
|
Lower intake was in good shape cleaned it up and painted it as well.
|
|
|
Painted the alternator bracket, timing chain cover and valve covers as well.
|
|
|
Got my heads back decided I would knock out the head gaskets. Bought Felpro, they are clearly marked with a Front imprint on the gasket, make sure you have them facing the right way. You should have two engine dowells per side that will hold the gasket in place.
|
|
|
Both heads installed. Make sure you follow the torquing sequence on the head bolts. Always start in the middle.
|
|
|
Now that the heads are on, I decided to put the intake gaskets in place, since they will need to set up.
|
|
|
The Felpro kit instructs you to run a 1/16th inch bead along this cork gasket and to put a drop a each corner where it meets with the intake gasket.
|
|
|
New fuel pressure regulator, I'm using the fuel rail from a '94 P/U so the design is different, much easier to access.
|
|
|
The manual calls for you to lightly oil the o-ring to help with installation of the injector..Even with the oil, it was still a chore getting these seated. You'll know when they're in.
|
|
|
Bolted the upper intake to the lower.
|
|
|
View from the top. The hardest bolt is the center one on the upper intake that uses a torx bit. You'll need to get creative with your extensions.
|
|
|
Bolted up the throttle body, used a new gasket.
|
|
|
Everything all together, still need an EGR, and a new IAC.
|
|
|
Crane cam P/N CRN 444-232 ordered from Summit.
|
|
|
They left the cam lube out, so I bought this at NAPA.
|
|
|
Lubed the cam thoroughly and installed it into the block rotating it as I pushed it in.
|
|
|
Installed the cam retainer
|
|
|
They went in easy enough.
|
|
|
Time for the push rods and the rocker arms.
|
|
|
Tighten the rocker arms to 35 - 50 ft lbs. The valve train is now done.
|
|
|
Now to install the timing gears and chain.
|
|
|
cam eccentric for mechanical fuel pump
|
|
|
This did not need to go on my motor.
|
|
|
At this point I should have replaced the harmonic balancer. The rubber inside the one from the factory was shot and several years later would let go causing me to have to replace it. Save yourself some time on the back end and buy a new one for your rebuild. Cheap insurance.
|
|
|
water pump on with new hardware.
added note: spend the money on a quality water pump, motorcraft preferably.
|
|
|
Laid a thick bead of RTV to seat the lower intake.
|
|
|
lower intake seated torque the bolts down to 18 ft lbs.
|
|
|
Mounting the alternator bracket, with new grade 8 hardware. The spot for the smog pump will be vacant as I'm eliminating it for this build.
|
|
|
Couldn't find any decent pulleys so I decided to just clean mine up, they were rusty. Used the wire wheel on my grinder. Here they are primed.
|
|
|
Installed the plugs, used some antiseize on the threads just to be safe, these are Autolite 24's, cheap copper but they work good, and gapped to .044. I'm going to run the MSD TFI coil so I may need to open them up a bit.
|
|
|
factory motor mounts were trashed.
|
|
|
BBK Header for the 351, these should help it breath a little better.
|
|
|
BBK header lined up with the EGR tube. This didn't work.
|
|
|
New exhaust, single Magnaflow muffler routed through 2 1/2 inch tubing with a single outlet, no cats and a custom y pipe.
|
|
|
351 waiting to be installed.
|
|
|
tired old 302, served me well.

|
|
What's wrong with this picture??
Answer, the rubber sleeve that acts as the dampener on the harmonic balancer has let go.
|
|
|
**WARNING** Replacement harmonic balancer from Summit notice the spacers. THIS IS NOT THE CORRECT WAY TO INSTALL..
|
|
|
This is the summit balancer installed the correct way with the centering ring in place. looks good.
